| Abstract: |
| Open burning of agriculture straw residueis a common method to dispose waste after harvesting seasons in Henan Province.Based on the survey data, the air pollutant emission inventory of crop straw open burning in 2014 for Henan Province was established by using emission factor approach. Besides, the temporal and spatial distribution characteristics of air pollutant emissions were also presented in this paper. The results showed that the total emissions of CO2, CO, CH4, NMVOCs, NH3, BC, OC, SO2, NOX and PM2.5 from straw residues open burning in Henan Province were 1.210 45×107, 5.174×105, 3.27×104, 7.19×104, 5.9×103, 4.2×103, 2.47×104, 5.5×103,3.13×104 and 7.48×104 t in 2014.Wheat and maize were the main sources of air pollution in Henan Province, with the contribution rate 38%~67% and 17%~36%. Spatially, the cities of Zhumadian, Zhoukou, Nanyang and Shangqiu were the highest value areas of atmospheric pollutant emission in Henan Province. Temporally, the emissions were concentrated in June and October,with the contribution rate 37.1%~65.7% and 11.3%~37% respectively. The research results will provide scientific basis for improving the regional environmental air quality in Henan province. |
